| Abstract: |
| 目的 综合评价中国不同地区人群内皮型一氧化氮合酶基因G894T(Glu298Asp)多态性与原发性高血压的关系.方法 以高血压组和对照组基因型和等位基凼分布的OR值为统计最,检索相关文献;应用MIX软件对各研究结果进行一致性检验和分析,并进行数据合并,评估发表偏倚的影响.结果 共10篇文献纳入Meta分析,包括1900例原发性高血压患者和1216例对照者,10篇文献中高血压组与对照组(GT+TT)/GG基因型频率和T/G等位基因频率OR值效应量的一致性检验结果均显著(P=0.013;P=0.011),并存在发表偏倚(P=0.049;P=0.038).高血压组与对照组(GT+TT)/GG基因型频率的合并OR值(95%CI)为1.79(1.33～2.42),显著性检验Z=3.83,P<0.001.高血压组与对照组T/G等位基因频率的合并OR值(95%CI)为1.73(1.32～2.27),显著性检验Z=3.92,P<0.001.结论 中国人(汉族为主)内皮型一氧化氮合酶基因894G→T多态性与原发性高血压相关. |

| Objective To evaluate the relationship between G894T(Glu298Asp) polymorphism in the endothelial nitric oxide synthase (eNOS)gene and essential hypertension in Chinese population from difierent regions.Methods Odds ratios(ORs) of G894T genotype and allele distributions in essential hypertension patients against healthy controls were analyzed.All the relevant studies were screened with poor-qualified studies eliminated.Meta-analysis software MIX(Meta-analysis with interactive explanations-version 1.71),was applied for investigating and analyzing heterogeneity among individual studies and summarizing the effects across studies,and the risk of publication bias was evaluated.Results A total of 1900 cases and 1216 controls from 10 studies were included.The heterogeneity between studies Was significant(P=0.013;P=0.011) and there were substantial sources of Publication bias(P=0.049;P=0.038).The pooled OR(with 95% CI) of GT+TT vs.GG genotype was 1.79(1.33-2.42)(Z=3.83,P<0.001),and the pooled OR (with 95% CI) of T vs.G allele Was 1.73(1.32-2.27)(Z=3.92,P<0.001).Conclusion In Chinese population,mainly the Hans ethnic group,894G→T mutation in the eNOS appeared to be related to essential hypertension. |
